    Question ffg vs fffg

    I reload 45-70 for my 1884 trapdoor. I am getting low on ffg BP and finding a local source is next to impossible. So, I was wondering, can I use fffg as a substitute? I load 70 grains of ffg (weighed) behind a 500 grain lead boolit. Advice welcome and thank you.

    While I use FF for .45-70, a number of the guys I shoot BPCR with use FFFg for the .45-70. Probably the only issue might be increased fouling. What ever you put in the case will be pretty much a solid cake after sufficient compression to seat a 500-550 grain bullet.

    If your bullet will still make contact with the powder. Try 65 grs of the3f , that should give you the same velocity as the 70 grs of 2.

    The FFFg will give as Don M has said more velocity with less powder. You may even mix the two powders. I find in shooting SASS matches that the FFF gives less fouling. I have been shooting a mix of BP that has shown some good results. Equal amounts of both FF and FFF in 44-40 cases for SASS matches. The accuracy is just as good or better and the fouling is much less with a easier clean up. You will also find those who use the FFF in the 45-70 case to shoot BPCR as Don C posted.
